Bangs, Wakefield, Mass., assignor to Forest Wadding Company,Roxbury, Mass., a corporation of` Massachusetts Application July a,1935, serial No. 29,593

5 claims. (o1. 229-14) The present invention relates to the art ofHpackaging, particularly for the purpose of preserving food in itsoriginalcondition. Such packing may be commonly used for packing meats',sh, dairy products or perishable vegetables during shipment, and alsoduring the time they are exposed for sale.

In the present invention the container may sometimes be used more thanonce, but more often the container becomes soiled or wet after beingused so that it cannot be used continually and must therefore bereplaced. It is essential for this reason to make the container ascheaply as possible and yet in such a manner that it will efficientlyand readily accomplish the purpose for which it is used.

The present invention is concerned more particularly with providing aninexpensive method of packing, particularly for such food stuffs as areperishable during shipment.

The present invention is an improvement on my previous applicationSerial No. 639,265, and inasmuch, is a more convenient and inexpensivecontainer which in cases is preferred to the container of the priorapplication.

The present invention will be more fully understood in connection withthe following description and the drawing showing an embodiment of thesame, in Which:-

Figure 1 shows an interior liner of the container.

Figure 2 shows a section through the container in its open position,

Figure 3 the container entirely in a closed position, and,

Figure 4, a section through the inner liner of Figure 1.

The container is shown as it is used in Figure 3. In this ligure lindicates the outer box which may be constructed of corrugated paperwalls with the lutings at the inside. The box may be made of one piecein the usual fashion with the top and bottom covers 2 and. 3. Within thebox is held the inner container 4, which comprises a non stiff orflexible bag element 5 having a stiff bottorn cover 6 as indicated moreclearly in the other gures. The bag element 5 may have waterproof facepapers such as 'l and 8 shown in Figure 4 with insulating elements 9between which may be batting or ground paper or some other suitablelight exible insulating material.

As indicated in Figures 1 and 4, the inner liner is composed of theinner sheet 'l and the outer sheet 8. These sheets form a continuouslining element about the inside walls of the container.

The edges of the sheets may be lapped over or closed over by cornerelements l0 as indicated in Figure l. The edge of the liner ispreferably capped b-y a border Il adhered to the end face edges of bothinner and outer sheets. The lower end may be sealed off if desired, butthis may preferably be left open where the insulating material 9 withinthe sheets is such that it will not easily come out. This is true in thecase of batting or wadding, and particularly in the present in ventionwhere the lower end is sealed when the container is in use as will bepresently described.

At the lower end of the liner or inside container 4, there is found astiff corrugated sheet I2 which passes about the entire end of thecontainer forming a border of the same. This corrugated sheet is gluedor adhered to the lower end of the liner as indicated at I 3. Justopposite the end I4 of the liner is positioned a scoring line VI5 uponwhich the corrugated element is folded when the lower end of the lineris closed to form the bottom of the inner container.

As indicated in Figure 1, the corrugated paper is cut at the corners l1so that they may be folded as an ordinary box. The corrugated board orpaper l2 in being folded, folds over the lower end I4 of the liner thussealing effectively the batting at the end. The lower 'end in its foldedposition forms a sti at bottom over the inner container, and providesas` is indicated in Figure 3 horizontal flutings I8 for circulation ofthe air within the container about the bottom of it, the container 4itself not tting so tightly but what the circulation at the sides ispossible. The top part of the container 4 may be closed over asindicated by the closing flaps I9 in Figure 3, and if desirable, arefrigerant may be placed above this.

The whole container, comprising the inner and outer elements may beshipped as one in a flat package with the ends lying flatly opened asindicated in Figure 2. The package may be assembled by first folding inposition the lower aps of the corrugated board l2 of the inner containerand then the outer cover 3 at the bottom of the outer container. Thepackage may then be lled and covered, complete circulation beingprovided by'ensuring an air space between the flutings on the bottompart of the cardboard l2 which places the cardboard I2 above the bottomof the box.

If it is desired the refrigerant may be placed in the top of the boxabove the stiff pad to insure that the refrigerant will not come indirect contact with the material, and in this case, circulation willtake place about the sides of the inner container and around the bottombetween the flutings and the bottom of the outer container.

Having now described my invention, I claim:-

1. A container comprising an outer cardboard case, an inner containerfitting within the same and substantially filling the space therein,said inner container having flexible Walls composed of sheets of paperin face to face relation with a layer of wadding therebetween, acorrugated sheet applied about the ends of the walls andl slit to formbottom covers for the inner container.

2. A container comprising an outer cardboard case, an inner exiblecontainer having an open top and comprising flexible walls formed of twosheets of parallelly disposed paper with a heat insulating layertherebetween, a corrugated sheet at one end of the walls forming acontinuous border about the end thereof and cut at the corners wherebythe sheets may be folded over to form a bottom of the inner container.

3. In a container of the type described, an inner liner comprising anelement of iiexible outer material and inner heat insulating material,

said element being closed on four sides, a corrugated sheet attached toone end of the enclosed element and forming an end of a bag, saidcorrugated sheets being cut at the corners whereby they may be folded toform the bottom of the bag.

4. A container of the type described, an insulating liner having wallsof outer paper elements and inner insulating material, a corrugatedcardboard sheet attached atthe lower end of the liner on the externalside thereof, said corrugated sheet being scored at a point just abovethe end of the liner whereby when the sheet is folded over to form thebottom of the inner container, the liner is sealed off at the end.

5. In a container of the type described, an inner liner composed of twoexible paper sheets having insulating material therebetween, meanssealing the insulation in the liner at one end and a corrugated sheetextending about the other open end, said corrugated sheet being scoredabout said end just above the end of the liner, said sheet being alsocut so that it may be bent lto form a bottom over the liner.
